7014 CD/HCP4ATBTA Bearing Product Overview & Core Advantages
The 7014 CD/HCP4ATBTA is a high-precision angular contact ball bearing supplied as a matched triplex set in a back-to-back (TBT) arrangement. Engineered for ultra-high rigidity and exceptional running accuracy, this bearing is designed to handle combined loads (radial and axial) simultaneously. The use of ceramic balls and a P4A super-precision tolerance class makes it ideal for applications demanding high-speed operation, minimal thermal expansion, and maximum operational reliability in demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7014 | Basic bearing series and size designation (70mm Bore, 110mm OD). |
| CD | Specifies a 15° contact angle and high-precision geometry. |
| HC | Indicates the use of Hybrid Ceramic balls (Silicon Nitride). |
| P4A | Denotes a super-precision tolerance class, tighter than ABEC 7. |
| TBT | Identifies the bearing as part of a Triplex Back-to-Back matched set. |
| A | Specifies an Extra Light preload on the matched set. |
7014 CD/HCP4ATBTA Bearing Structural Features & Performance Benefits
Unmatched Rigidity and Stability: The triplex back-to-back arrangement creates an exceptionally stiff bearing system that resists moment loads and shaft deflection, crucial for maintaining precision under heavy combined loads.
High-Speed & Low-Temperature Rise Performance: The hybrid ceramic balls are significantly lighter than steel, reducing centrifugal forces. Combined with the lightweight phenolic cage, this allows for a high limiting speed of 22,000 rpm with lower friction and heat generation.
Extended Service Life and Reliability: Ceramic balls are harder, more wear-resistant, and electrically insulating. They also operate effectively within a broad temperature range (-30°C to 110°C). The bearings are pre-lubricated for immediate operation.
Precision Running Accuracy: Manufactured to P4A tolerance class with a 15° contact angle, this bearing ensures minimal runout and vibration, which is essential for applications requiring extreme positional accuracy.
